VAPOR-STOVE.

SPECIFICATION forming part of Letters Patent No. 308,563, dated November25, 1884-.

Application filed November 10, 1883. (No model.)

To all whom it may concern.-

Be it known that I, XVALTER E. KAUKE, a citizen of the United States,residing at Bryan, in the county of WVilliams and State of Ohio,

have invented certain new and useful Improvements in Vapor-Stoves; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

Figure 1 is a vertical longitudinal section through the improved stove.Fig. 2 is a rear endview of the valve-seat. Fig. 3 is a side view, withparts broken away, of the reservoirs and valve, the latter being insection. Fig. 4 is an end view, with parts broken away, of thereservoirs and valve, the latter detached from its seat.

My invention has reference to that class of gasoline or vapor stoves inwhich the burning-fluid is forced to the burners by compressed airacting on the surface of the fluid in the fiuid-holding chamber, and myimprovements relate to the means for supplying the air to saidfluid-holding chamber; and they consist in combining with the chambertwo rotating reservoirs communicating with each other and alternatelywith the fluid-holding chamber, and adapted to serve alternately as aliquid and then as an air vessel, so that liquid in the upper reservoirmay pass therefrom into the lower reservoir and compress the air in saidreservoir, so as to force it therefrom into the fluid-holding chamber,and after the air in the lower reservoir has been displaced by theliquid said reservoir may be rotated to the top and the other reservoirto the bottom and into communication with the fluid-holding chamber, andthe supply of air continue as at the beginning.

The improvements further consist in the construction and the combinationof parts hereinafter particularly described, and then sought to bespecifically defined by the claims.

In the accompanying drawings, the letter A indicates the stove-frame,which supports in its lower portion the fluid-holding chamber B, whichis provided with a screw-capped opening for the introduction of theoil,and has a pipe, 0, leading upward therefrom and across the frame underthe top plate, D, of the stove,

along which it is provided with any desired number of valve-controlledburners, E.

There is nothing novel in the construction of the parts just referredto.

To one end of the frame, near its top, there is secured a valve withregistering ports. The valve is composedpf two parts, oneof which(indicated by the letter F) I will designate as the seat and the other(indicated by the letter F) as the valve. formed with a raised face, f,and may be provided on its rear or back with an angular stud, f, to fitinto a recess or opening formed in the end of the stove-frame, so as toprevent the seat from turning. Any other means than that used may beemployed to prevent the seat from turning, and the face may be omittedwithout departing from the spirit of my invention. The seat and its faceare provided with a port, f which registers with the mouth of the pipeG, which leads to the The seat is preferably.

fluid-holding chamber, and the valve is provided with two ports, f j,which may be diametrically opposite to each other, and made to registerwith the port f when brought opposite thereto. The valve is held to itsseat so as to be permitted to turn thereon by a bolt, H, which alsopasses through the seat and the face and the end of the stove-frame, andholds the several parts together when the nut h is screwed onto its end.That portion of the belt which fits in the seat is preferably square, sothat the bolt will not turn when the valve is revolved or turned on therounded portion thereof but any other means for effecting the sameresult may be adopted.-

Two vessels or reservoirs, I and I, are made to communicate with theports f and 1, respectively, by means of pipes J and J, and with eachother by means of pipes K and K, which extend from the adjacent end ofone reservoir into the opposite reservoir, and preferably nearly to thefarthest removed end thereof. The pipes K and K are provided between thereservoirs with cocks L and L, respectively, the spigots of which areweighted, so as to drop by gravity, and thus automatically operate thecocks, one being applied so as to open communication between the tworeservoirs through its pipe, while the other at the same time closescommunication through latter is brought under the same.

its pipe, and thus communication is had through only one pipe at a time.The chamber of each cock is formed with a shoulder, Z, and the spigotprovided with a pin, Z, to strike against the said shoulder, and thuslimit the movement of the spigot, so that it will not swing beyond thepoint of closing the cock.

In the outer ends of the reservoirs I and I there are placed cocks M M,which are provided with weighted spigots m an, operating by gravity toclose one cock when its reservoir is lowermost and to open the otherwhen its reservoir is uppermost. These cocks are also provided withshoulders and pins like the others, for the same purpose. The reservoirI is provided with a screw-capped nozzle, N, through which liquid may beintroduced into the same, and, if preferred, the other reservoir may beprovided with a similar nozzle.

For the purpose of holding the reservoirs in a perpendicular position,notches 0 0 may be formed in the periphery of the valve, and atongue orlatch, 0, may be hinged to the seat, so as to fall into either notchwhen the These notches will be so located that when the tongue enterseither, one of the ports in the valve will be registering with the portin the seat, and communication will be open between the lowermostreservoir and fluid-holding chamher. A third notch, 0 may be formed inthe valve, so that when the tongue fits therein neither port willregister with that in the seat, and hence communication between thereservoirs and fluid-holding chamber will be closed, and there will beno pressure 011 the oil to force it up to the burners, and hence therewill be less evaporation of the same.

A set-screw passed through the valve so as to bear against the seatmight be used,instead of the hinged tongue, to lock the valve to itsseat; but the tongue is preferred, as it will drop into the notch andlock the parts, and thus avoid liability of the parts being leftunlocked.

The operation is as follows: The uppermost reservoir is filled orpartially filled with water or other suitable liquid, and all the cooksbeing closed except that in the upper end of the uppermost reservoir andthat in the pipe K, the water runs from the uppermost reservoir into thelowermost one through the pipe K and gradually displaces the airtherein, forcing it upward through pipe J and the registering ports ofthe valve into the pipe G, and thence down onto the top of the oil inthe fluidholding chamber, thereby displacing the oil and forcing it upthrough the pipe to the burners. The relative size of the reservoirs andoil-chamber and connecting-pipes may be such that the pressure of theair will not be more than sufficient to raise oil enough to supply thedemand of the burners or the flow of the oil may be controlled by thevalves to the burners. As the water runs out of the reservoir I it drawsair into said chamber through the open cock at the top thereof, andafter all the water, or so much thereof as is deemed neces sary, has runoff into the lowermost reservoir the valve is unlocked and the lowermostres ervoir raised to the top. The pipe J and its port have now beenbrought to register with the port of the seat, and communicationestablished between reservoir I and the fiuidholding chamber. W'hileraising the lowermost reservoir the weighted cocks have turned so as toclose communication by way of pipe K and cook M. and open it betweenpipe K and cock M, so that the operation will be the same as before,only the parts will be reversed in position. It will be seen that bysuch a construction and combination as described air will be supplied tothe fluid-holding chamber to force the oil to the burners without thenecessity of pumping by hand or other laborious means to obtain therequired pressure therefor. One reservoir has only to be filled, and theoperation then proceeds without further labor until the reservoir isemptied, and then you have only to reverse the position of the parts andthe operation continues with out cessation. The pressure of air on theoil in the chamber might be said to be continuous, for before thepressure of air supplied to the chamber from the reservoir has exhausteditself the reservoirs have been reversed and the supply of air renewed.

The device is simple in construction, cheap of production, durable, andnot easily put out of working order.

Having described my invention, what I claim 1s- 1.
